TL;DR
PCD-CT LIE demonstrated the highest CNR at 40-keV VMI with 2-mm slice thickness, regardless of scar pattern, BMI, or ICD presence, regardless of scar pattern, BMI, or ICD presence.
PURPOSE To compare the performance of different reconstruction kernels and sharpness levels in photon-counting detector CT (PCD-CT) for post-transarterial chemoembolization (TACE) imaging of hepatocellular carcinoma (HCC), with particular emphasis on residual viable tumor conspicuity, and to identify reconstruction set...
Background/Objectives: This study aimed to investigate the impact of low-energy virtual monoenergetic imaging (VMI) on quantitative and qualitative image characteristics, as well as its effect on the diagnostic assessability of thoracic arteries in photon-counting computed tomography angiography (CTA). Methods: We retr...
While UHR acquisition provides highest image quality in PCD-CT cCTA, lower-dose acquisition modes achieve comparable diagnostic accuracy for coronary stenosis detection and Protocol selection should therefore be individualized, and prospective controlled studies are required.
To determine the best combination of reconstruction parameters on a spectral photon-counting CT (SPCCT) system to improve detection of peritoneal metastases (PMs) on virtual monoenergetic images (VMIs) at 40 keV. A spectral phantom was scanned using SPCCT and dual-energy CT (EID-DECT) at 8.5 mGy (CTDIvol). 40 keV VMIs...
To investigate the clinical application value of multi-parameter imaging with dual-layer detector spectral CT (DLCT) for GTH visualization. A total of 61 patients who underwent abdominal portal venous phase-enhanced SLCT were retrospectively enrolled. The raw image data were reconstructed into 120 kVp conventional imag...
Color K-edge imaging is feasible with multiple high-Z elements, whilst outperforming the performance of conventional imaging, paving the way for lung SPCCT functional imaging.
